7.CAUTIONS
(1) Cautions
· The devices are UV light LEDs. The LED during operation radiates intense UV light,
which precautions must be taken to prevent looking directly at the UV light with unaided eyes.
Do not look directly into the UV light or look through the optical system. When there is a possibility
to receive the reflection of light, protect by using the UV light protective glasses so that light should not
catch one’s eye directly.
· Put the caution label on the cardboard box.

(2) Lead Forming
· When forming leads, the leads should be bent at a point at least 3mm from the base of the lead.
Do not use the base of the leadframe as a fulcrum during lead forming.
· Lead forming should be done before soldering.
· Do not apply any bending stress to the base of the lead. The stress to the base may damage the LED’s
characteristics or it may break the LEDs.
· When mounting the LEDs onto a printed circuit board, the holes on the circuit board should be exactly
aligned with the leads of the LEDs. If the LEDs are mounted with stress at the leads, it causes
deterioration of the lead and this will degrade the LEDs.
(3) Storage
· The LEDs should be stored at 30°C or less and 70%RH or less after being shipped from Nichia and
the storage life limits are 3 months. If the LEDs are stored for 3 months or more, they can be stored
for a year in a sealed container with a nitrogen atmosphere and moisture absorbent material.
· Nichia LED leads are gold plated Iron alloy. The gold surface may be affected by environments which
contain corrosive substances. Please avoid conditions which may cause the LED to corrode,
tarnish or discolor. This corrosion or discoloration may cause difficulty during soldering operations.
It is recommended that the LEDs be used as soon as possible.
· Please avoid rapid transitions in ambient temperature, especially, in high humidity environments where
condensation can occur.
